11 Claims.

This invention relates to window constructions, particularly for railwaycars, motor busses, and the like, and has for its object, a particularlysimple and adjustable means for applying a predetermined pressure to thewindow stop for holding the sash tight against rattling without bindingthe sash in its guide.

The invention consists in the novel features and in the combinations andconstructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanyingdrawings in which like characters designate corresponding parts in allthe views.

Figure 1 is a fragmentary elevation of a window construction embodyingthis invention.

Figure 2 is an enlarged, sectional view on line 2-2, Figure 1.

Figure 3 is a fragmentary inner face view of one of the stops.

Figure 4 is a detail view of the screw threaded socket for receiving theadjusting screws for the adjustable stop.

Figure 5 is a fragmentary view of one of the outer stops.

In window constructions, such as are used in motor busses and the like,the window sashes must be held sufficiently tight to prevent rattling,and at the same time be capable of being raised and lowered withoutbinding.

At the outset, window stops can be arranged so as to so hold the sashes,but during use, because of dust and the like finding its way into thesash guide and there being no place for the dust to work out, the sashesbecome difficult to raise and lower.

Ihe principal feature of this invention is means by which this conditioncan berelieved quickly by adjusting one of the window stops, usually theinner stop.

1 designates the usual upright frame members or posts of a window frame.

2 and 3 designate respectively outer and inner stops which form a guidefor the stiles e of the sash 5, one of these steps, usually the innerstop,

, being spring pressed with a predetermined spring pressure againt thesash.

One feature of the invention is the adjusting of this spring pressure,or adjusting the thrust or pressure of the adjustable or inner stopagainst the sash, so that the sash will work without rattling andwithout binding.

The outer stop 2 which, in this embodiment of my invention, is notadjustable, may be of any suitable form, size and construction, it beinghere shown as right angular in cross section with one flange forming theouter stop, and the other flange '1 seating against the post.

The adjustable inner stop 3 is channel shaped in cross section with thebottom 8 of the channel lapping the inner face of the frame member orpost 1, that is, the face toward the interior of the vehicle, with theside flanges of the channel spaced apartfrom the side faces of the framemember or post 1, and with inturned flanges 9 at the entrance of thechannel formation, which flanges thrust against the stiles 4 of thesashes.

The stop 3 is thus double construction and angular in cross section,open at one side, and with the open side toward the frame member orpost 1. The stop 3 is secured to the post or frame member 1 so as to beyieldingly pressed against the sash or sashes by springs, and thetension of the springs adjusted to adjust the thrust or grip of the stop3 on the sash or sashes.

10 designates springs located within the stop 3 on opposite sides of thepost or frame member 1 and interposed between the flanges 9 and theopposite ends of a spring abutment or plate 11 extending transversely ofthe outer face of the frame member or post 1 under and spaced from thebottom flange 8 of the stop 3. The abutment is here shown as slidablymounted'upon studs 12 secured at like ends to the bottom 8 of thechannel formation, and at their other ends extend into the flanges 9,and the springs 10 encircle said studs.

The means for securing the abutment to the frame member or pillar 1 andadjusting it to adjust the tension of the springs 10 comprises a memberas a screw 14 extending throughthe bottom 8 of the channel shaped stop 3through the abutment and threading into the frame member or post 1, thescrew having its head 15 thrusting against the outer face of theabutment 11, so that as the screw is tightened, the abutment will bemoved inwardly toward the frame member or post 1, thus compressing thesprings so that they act with greater force against the flanges 9 andthus thrust the stop 3, or the flanges 9 thereof with greater forceagainst the sash or sashes. Loosening of the screw lessens the thrust orforce of the springs against the flanges 9. Owing to the mounting of theabutment 11 with the screw located between the ends of the abutment andbetween the springs, it has a rocking or equalizing action against theupper ends of .thesprings 10. For the end windows, where the pillar orframe member 1 does not separate two window constructions, any suitablemember may be substituted for f one of the sash stiles for the stops tothrust against.

The screws 14 preferably thread into a longitudinally split threadedsocket provided in the frame member or post 1. 16 designates the socketsplit longitudinally at 17, and having a face plate 18 at its outer endoverlying the face of the frame member or post 1 and secured thereto inany suitable manner, as by screws 19. The socket is first threaded andthen split, and then the sections thereof compressed inwardly so thatwhen the screw is turned in the socket, the sections of the socket gripthe screw and hold it from unintentional turning. There may be one ormore abutments 11 and companion springs 10, and adjusting screws 14spaced along the outer stop, and there are usually three of sunabutments near the upper and lower ends and midway between the ends ofthe stop.

The heads of the screws 14 are preferably formed so that a special tool,wrench, or screw driver, is required to operate them, whereby the screwscan be adjusted only by authorized persons. As shown, the heads of thescrews are formed with spaced holes 29 requiring a tool with similarlyspaced prongs.

The inturned flanges 9 of the stop are preferably provided with wearstrips 21 for engaging the sashes, which strips are secured thereto inany suitable manner, as by rivets 22. The stop 3 is usually formed ofsteel and finished to represent wood, or in any other manner, and thewear strips are brass to coact with sheet metal hollow stiles of thesashes. The angular stops 2 are also preferably brass.

25 is a facing or trim strip for the outer side of each post 1, thesebeing in the general form of a channel embracing the post with thebottom of the channel the post, and the side flan es 28 lapping the sashsides of the post and provided with angular 27 lapping the flanges 28 ofthe angular outer stop 2. v The facing strip 25 is permanently securedto the post as by screws 29, and is not intended to be removed. It isusually steel enamelled, painted, or otherwise finished.

Usually, the stops 2 are secured to the post 1 rather than to the facingstrip 25, and aresecured to the post, as by screws 30, extending throughthe flange 7 of the stop 2, which flange '7 seats against the post.

The flanges '7 of each of the stops 2 are provided with holes 32 forreceiving the bolt of a sash holder or lock 33, which. bolt movesthrough the edges of the sashes, the post 1 being provided with bores 34alined with the holes. 32 for receiving the ends of the bolts.

The sash locks or holders 33 may be of any suitable construction, andthere is usually a sash lock or holder at the lower corners of eachsash.

Each includes a finger lever 36 which is connected, through any wellknown mechanism, to the bolt. r

In operation, when the sash is first inserted, the inner stop 3 isadjusted by turning the screws 14. After the sash has been in use andthe sash guide fills more or less with dust, or other material, tendingto cause it to bind with such initial adjustment, the screws 14 can beunscrewed slightly, as a quarter or half turn, thus relieving thetightness.
